Captain Britain and MI:13

A vampiric invasion has targeted the United Kingdom. His minions have infiltrated MI:13, leaving Wisdom and the team stuck trying to purge the traitors in their midst. But he's got obstacles in claiming Britain for his own. Upon his death, noted vampire hunter Quincy Harker had his friends use his remains to cast a powerful spell to protect the country from vampires. Before they can enter the country, each one must be invited personally. On the moon, Spitfire finds herself in Dracula's thrall. Unable to resist, or to violate his will, she's forced to assist in his plans.
